Abstract

The invention discloses treatment apparatus for condensable particulate matter and moisture in flue gas. The treatment apparatus is provided with a shell; a first region, a second region and a third region which communicate with each other are sequentially arranged in the shell along the horizontal direction X, wherein first tube bundle heat exchangers and a first liquid collecting tank located below the first tube bundle heat exchangers are arranged in the first region; spraying devices and a second liquid collecting tank located below the spraying devices are arranged in the second area; andsecond tube bundle heat exchangers and a third liquid collecting tank located below the second tube bundle heat exchangers are arranged in the third region. The invention further provides a treatmentmethod of the condensable particulate matter and moisture in the flue gas and a coal-fired flue gas treatment system comprising the treatment apparatus. The treatment apparatus and the coal-fired flue gas treatment system can effectively remove the condensable particulate matter and moisture in the flue gas, so that phenomena such as gypsum rain, wet smoke rain and the like can be reduced or eveneliminated.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a treatment device for condensable particulate matter and moisture in flue gas and a coal-fired flue gas treatment system. Background technique [0002] According to the "Action Plan for Clean and Efficient Utilization of Coal (2015-2020)", the coal power industry is gradually accelerating the development of high-efficiency coal-fired power generation and upgrading to achieve clean and efficient utilization of coal. At present, coal-fired power plants are equipped with equipment such as desulfurization and denitrification, and electric dust removal, and have formed two ultra-low emission technology routes centered on wet electric dust removal and low-temperature electric dust removal in existing engineering practice. SO from coal-fired power plants 2 , NO x However, there is still a lack of effective control methods and methods for condensable particulate matter, ...
